The report, Review of Alien Fish Monitoring Techniques, Indicators and Protocols: Implications for National Monitoring of Australia’s Inland River Systems, is not intended to be an exhaustive review. It brings together fundamental information regarding alien fish to inform the National Vertebrate Pests Committee and the NLWRA regarding alien fish for monitoring and reporting under the National Natural Resource Management Monitoring and Evaluation Framework. The document presents a summary of: • alien fish species in Australia that have triple bottom line (environmental, economic or social) impacts • techniques available for measuring and monitoring pest fish distribution, abundance, and impacts 5 • current research and management programs that measure and report fish information • recommendations regarding fish monitoring and reporting under the National Monitoring and Evaluation Framework. This report also identifies knowledge gaps in the monitoring of alien fish and their impacts.
